Headphones (cue) not working with Denon MC3000

Hi everyone,
I just bought myself a Denon MC3000 and received a copy of CrossDJ LE (2.3.1) with it. I really like to try out this piece of software to determine which of the bundled software I will update (also received and trying Traktor already).
Now the issue is that with Traktor (also LE) everything is working just fine, but with CrossDJ, I can't get my cue through my headphones. I've tried several options, also the ones I found on this forum, but none of them solves the problem.
In preferences, I can select Direct Sound: Speakers (MC3000) or ASIO: Denon DJ Asio Driver.
Selected Routing Mode is Dual Stereo.
With Direct sound selection, the only output (1,2 or 3) option I have is Left/Right, so I can't put my cue through another output than my speakers.
With ASIO selected, I can select MC3000 1 / MC3000 2 or MC3000 3 / MC 3000 4 at input and output, but I can't load any tracks to one of the desks and I will receive an error which is saying to check my audio settings.
As said before, I tried all options (output modes, routing modes) but did still not manage to get it working.
Hope you guys can help out!
